If you’re experiencing issues with your 2016 Nissan Sentra key fob, a dead battery might be the culprit. Key fob batteries are designed to last for several years, but various factors can affect their lifespan. This guide will walk you through everything you need to know about your Nissan Sentra 2016 key fob battery, from identifying signs of a dying battery to replacing it yourself.
Identifying a Dying Key Fob Battery
Before you start troubleshooting, it’s crucial to identify the signs of a dying key fob battery. Here are some common indicators:
- Decreased Signal Range: You may notice that you need to be much closer to your car for the key fob to unlock or lock the doors.
- Intermittent Functionality: The key fob may work intermittently, sometimes requiring multiple presses for a response.
- No Response: In some cases, the key fob may stop working altogether, leaving you unable to lock, unlock, or start your car.
How to Change Your Nissan Sentra 2016 Key Fob Battery
Replacing your Nissan Sentra 2016 key fob battery is a relatively straightforward process that you can do yourself with just a few tools.
Tools You Will Need:
- Small flat-head screwdriver
- New CR2032 battery (widely available at hardware stores and online)
Step-by-Step Guide:
- Locate the key fob’s release button. This is a small button usually located on the back of the fob.
- Press the release button and separate the key fob’s two halves.
- Identify the battery compartment. This is usually a small slot where the battery sits.
- Carefully pry out the old battery using the flat-head screwdriver. Avoid damaging the battery contacts inside the fob.
- Insert the new CR2032 battery, ensuring the positive (+) side faces up.
- Align the two halves of the key fob and press them together until you hear a click.
Programming Your Nissan Sentra 2016 Key Fob
In most cases, you won’t need to reprogram your key fob after a battery replacement. However, if the key fob still doesn’t work after replacing the battery, you might need to reprogram it. You can find detailed instructions on how to program your Nissan key fob in your owner’s manual or online.
Extending the Lifespan of Your Key Fob Battery
While key fob batteries eventually die, here are a few tips to maximize their lifespan:
- Avoid frequent button presses. Each press consumes battery power.
- Keep your key fob away from extreme temperatures. Extreme heat or cold can drain battery life.
- Don’t stack your key fob with other key fobs or electronic devices. This can cause unnecessary signal interference and drain the battery.

- You’re uncomfortable disassembling electronic devices.
- You’ve replaced the battery, but the key fob still doesn’t work.
